I dont know about the ECS bracket system compared to the Vortech but Id imagine they are very similiar. This is the area that gave me the most trouble. There were alot of different size bolts and spacers that have to be assembled perfectly for the belts to track true. Take your time and it will be no problem. I didnt have a right angle drill so I just removed my radiator to pin the crank and it was easy. Also use a balancer install tool and you can put the balancer in the oven at 200 degrees for 20 min and it will slide on the crank pretty easy. Good luck and post pics.

Many people tackle this themselves without a problem, hopefully you do too. If you would like a start up tune file send me your ECM when you start the project and I'll turn it around the same day received.

It still needs to be checked, but it will be very close if not spot on and you can check the cars operation prior to dynoing.

Im either taking it to Lethal Performance or Henderson Performance, called both of them for a quate on a tune but didnt get a awnser from either one. Left a msg so hopefully ill hear something from them..

Pinning the crank is easy on the ECS kit. Don't have to remove the balancer. Also don't have to remove front bumper cover. Hardest part is figuring out what spacers go where. Study the install pics in the instructions as you do the install. ECS can explain what spacers go where. FSP helped me a lot, I bought from them and installed myself.
